Security OperationsmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is to isolate the endpoint from the network using the EDR containment feature. This is correct because containment stops the encrypted archives from being exfiltrated over SMB connections while preserving all running processes, memory, and disk state—critical for retaining volatile evidence like active malware processes and network connections. On the Security+ SY0-701 exam, this scenario tests your understanding of incident response procedures, specifically the priority of stopping lateral movement without destroying forensic data. A common trap is to shut down the machine or kill processes, which would wipe out volatile evidence; instead, remember that EDR containment is a surgical network block that leaves the endpoint frozen for analysis. Memory tip: “Contain, don’t kill—preserve the spill.”

SY0-701 Security Operations Practice Question

This SY0-701 practice question tests your understanding of security operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A SOC analyst receives an EDR alert showing a finance laptop creating encrypted archives and then attempting SMB connections to several internal file shares. The user is still logged in, and the business wants to stop possible spread without destroying volatile evidence. What should the analyst do first?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Isolate the endpoint from the network using the EDR containment feature.

Option B is correct because the EDR containment feature isolates the endpoint from the network while preserving all running processes, memory, and disk state. This stops the encrypted archives from being exfiltrated via SMB and prevents lateral movement, but keeps volatile evidence (e.g., active malware processes, network connections) intact for forensic analysis.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Power off the laptop immediately to stop all activity.

    Why it's wrong here

    This may stop the current process, but it can destroy volatile evidence such as memory contents and active connections.

  • Isolate the endpoint from the network using the EDR containment feature.

    Why this is correct

    This cuts off the host from reaching other systems while preserving the powered-on state, which helps protect volatile evidence.

    Clue confirmation

    The clue word "first" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Reimage the laptop from a gold image as soon as possible.

    Why it's wrong here

    Reimaging is a recovery step, not the first containment action, and it would remove evidence needed for analysis.

  • Disable the user account in Active Directory and wait for the malware to stop.

    Why it's wrong here

    Account disablement may limit some actions, but it will not reliably stop malware already running on the endpoint.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse 'stopping the spread' with 'destroying evidence,' and choose power-off or reimage, failing to recognize that containment in EDR is designed specifically to halt network propagation while preserving forensic data.

Detailed technical explanation

How to think about this question

EDR containment typically works by applying a host-based firewall rule that blocks all inbound and outbound traffic except to the EDR management server, often using Windows Filtering Platform (WFP) or iptables. This preserves the process memory, which can be dumped for analysis of encryption keys or C2 communication artifacts, while preventing SMB (port 445) and other lateral movement protocols from reaching internal shares.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.

Same concept, more angles

1 more ways this is tested on SY0-701

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A SOC analyst reviews an EDR alert showing powershell.exe launched with an encoded command, then immediately connected to an unfamiliar IP address and spawned rundll32.exe. The user is still logged in and the machine may still contain evidence needed for investigation. Which two actions should the analyst take first to contain the incident while preserving evidence? Select two.

hard
  • A.Isolate the endpoint using EDR network containment or a quarantine policy.
  • B.Disable the user account and revoke active sessions or tokens for that identity.
  • C.Reboot the workstation immediately to clear any malicious process from memory.
  • D.Run a full vulnerability scan before taking any other action.
  • E.Delete the suspicious email from the mailbox to remove the original payload.

Why A: Option A is correct because isolating the endpoint via EDR network containment or quarantine policy immediately stops the malicious process from communicating with the command-and-control (C2) server at the unfamiliar IP address, preventing data exfiltration and lateral movement. This action preserves the volatile evidence in memory (e.g., the spawned rundll32.exe process) and on disk, allowing forensic analysis without the risk of the attacker destroying evidence remotely.
